I saw that. I felt bad because I snickered at first when I saw the comments saying, "God is with them!"

Bury me with my guns on, so when I reach the other side - I can show him what it feels like to die.
Bury me with my guns on, so when I'm cast out of the sky, I can shoot the devil right between the eyes.

Trafic as this event has been, this is the kind of things the mainsstream religions use to make people want to believe in God. "If that young man would have met God, he wouldn't have done that" "The victims are now in abetter place, they are with God now" and all those cliche phrases.

Personally I can't help to wonder what was the reason for the shooter to do it?

I think it should definitely be looked into as a possible hate crime as well. It would be rather fucked up if they were shot merely for being Christian.
I may not agree with christianity, but the hell if I want their children being murdered JUST for being christian anymore than I would want children murdered JUST for being atheists.
